Ventus,Roxas and Axel popping up felt like a Deus Ex Machina. I have touched DDD so I am not sure how aware is the soul of Ventus or for that matter his heart, I know Axel became Lea again along several members of Org XIII.

Why do we need to to know about their breasts sizes? And remove the bit of Xion cutting her hair, is obvious from the get to go if it isnt as long as Hinata she trims it.

"Naruto's parents Minato and Kushina, used a seal that did seal the fox demon in Naruto, but also sealed part of themselves in him as well, that way the two could eventually meet there son as a young man, and tell them about Madara and his plan to rule your world."

How the fuck Yen Sid knows about this? Only the Sandaime had a vague idea of it, and only a vague idea he did not know for certain, how does he knows about it?

Hiashi conceded a bit too easily the entire training trip... Hinata is both a clan heir and a unsealed byakugan, having her going in a journey is something Hiashi would frown upon, for the single reason that her eyes might get stolen, he also does not knows Xion, so at the very least he should summon her and evaluate her before giving the green light.

Interesting route you are following with Neiji and Isnt Hinata gaining techniques a bit too fast? I get it if this were BBS you would be able to pull it off given teh sheer ease you can have to create commands.
